Our high quality bed bug covers will not only lock bed bugs in, but help to make re-treatment easier by preventing any further infestation in and on the mattress and box spring. Mattress encasements enclose your mattress and box spring and are an integral step in the treatment process for two reasons: 1. They protect your investment in bedding. 2. They reduce the areas where bed bugs can hide nearest to where you sleep. The water-resistant, tight-weave fabric prevents the entry of even the smallest bed bug.
